Perfect Dark's Combat Simulator is a beautiful thing. Let us bask in its
magnificence. Let us write tomes of sonnets proclaiming its brilliance. Let
us find the game's creators and love them family-style. Oh, screw it, let's
pick up a controller and get busy. The Combat Simulator provides control
over every single minute detail of gameplay. It is the gamer's game.

Access the Combat Simulator from the main PD menu. Then, start fiddling.
Although the menus can seem overwhelming, we've broken them down, explaining
details and providing insight on how to custom-make the ultimate multi-player
experience. To get you into the right mood, we've come up with a menu of
our own -- that floating gray red thing at the top right. From there, you
can access three different sections:
Challenges, Preset
Games and Advanced Setup.
